Abstract

L'invention porte sur une hotte à aspiration, qui comprend une chambre ventilée ayant une ouverture d'accès. Un premier ensemble profil allongé est fixé à une partie de bord d'un plancher qui s'étend à partir de l'ouverture. Un châssis de fenêtre est monté de façon à pouvoir coulisser à l'ouverture d'accès, et un second ensemble profil allongé est fixé à un bord inférieur du châssis de fenêtre. Le premier ensemble profil allongé comprend une pluralité d'aubes allongées en relation mutuellement espacées verticalement, qui définissent des canaux d'écoulement d'air. Le second ensemble profil comprend une paire d'aubes allongées en relation mutuellement espacées verticalement, qui définissent des canaux d'écoulement d'air qui s'étendent dans la chambre. Un ensemble écran est disposé devant une paroi arrière de la chambre, et comprend un panneau primaire ayant une pluralité de fentes de sortie d'air verticales adjacentes à un bord inférieur, et un panneau tampon ayant une pluralité de fentes de sortie d'air horizontales adjacentes à une partie supérieure.
